Zodiac Revolution Plus by Richard Osterlind is a workable routine, but requires either an excellent
memory or cheat sheet. It also typically requires asking multiple questions, which tips that you may
be using an algorithm. The "plus" portion is a nice add-on and can be used with other Zodiac
routines, such as the one found in Sass' book, "120% Chestosterone." On the plus side, Osterlind
provides a large colorful folding chart of the Zodiac symbols and material to make up the cheat
sheet. I only have two Zodiac effects, Zodiac Revolution Plus and Sass' Zodiac. Both require an
excellent memory or cheat sheet. As a personal preference, I like Sass' approach if you are doing it
one-on-one and Osterlind's if you are doing a stage effect. If you need a Zodiac routine, I
recommend getting Zodiac Revolution Plus (and Sass' book if you can afford both). The price of
Zodiac Revolution Plus is fair ($15.60 at Penguin) and the instructions/props high quality. However,
be prepared to put in some practice using the supplied materials. This is not exactly self-working
effect, but the cheat sheet (supplied) does most of the work for you.
